使用

　　<div>弹窗中间内容</div>

  <div slot="footer"></div>
</full-screen-dialog>

 

1.template部分

<template>
  <transition name="fullscreen" @after-enter="afterEnter"
              @after-leave="afterLeave">//动画
    <div v-if="visible" class="fullscreen-dialog-wrapper" >
      <div ref="dialog" class="fullscreen-dialog">
        <div ref="header" class="dialog-header">
          <span class="dialog-title">{{ title }}</span>
          <a aria-label="Close" class="dialog-headerbtn">
            <i class="dialog-close el-icon el-icon-close" @click="closeMyself"></i>
          </a>

2.js部分

<script>
export default {
  name: 'FullScreenDialog',
  props: {
    title: {
      type: String,
      default: ''
    },
    visible: {
      type: Boolean,
      default: false
    },
    customClass: {
      type: String,
      default: ''
    }
  },
  data () {
    return {
      closed: false,
      appendToBody: true
    }
  },
  watch: {
    visible (val) {
      if (val) {
        this.closed = false
        this.$emit('open')
        this.$nextTick(() => {
          this.$refs.dialog.scrollTop = 0
        })
        document.getElementsByTagName('body')[0].className = 'el-popup-parent--hidden'
        if (this.appendToBody) {
          document.body.appendChild(this.$el)
        }
      } else {
        if (!this.closed) this.$emit('close')
        document.getElementsByTagName('body')[0].className = ''
      }
    }
  },
  mounted () {
    if (this.visible) {
      if (this.appendToBody) {
　　　　//将dom添加在body下面
        document.body.appendChild(this.$el)
      }
    }
  },
  methods: {
    closeMyself () {
      this.$emit('close')
　　　　//右上角关闭X号的事件
    },
    afterEnter () {
      this.$emit('opened')
    },
    afterLeave () {
      this.$emit('closed')
    }
  }
}
</script>
